Solenoid valve sealing cov ntaub ntawv, VITON fluorine roj hmab

VITON fluorine roj hmab (FKM)
Cov roj hmab uas muaj fluorine nyob rau hauv lub molecule muaj ntau hom raws li cov ntsiab lus fluorine, uas yog, cov qauv monomer; cov roj hmab hexafluorinated fluorine muaj qhov kub thiab txias zoo dua li cov roj hmab silicone, tshuaj lom neeg tsis kam, thiab tsis kam mus rau feem ntau cov roj thiab cov kuab tshuaj (ketones, esters) Tshwj tsis yog rau qeb), nws muaj huab cua tsis zoo thiab ozone tsis kam, tab sis tsis zoo rau cov khaub thuas; nws yog feem ntau dav siv hauv cov ntsaws ruaj ruaj rau tsheb, maus taus, cov khoom thib ob, thiab cov nroj tsuag tshuaj. Kev khiav hauj lwm kub yog -20 degree ~ 260 degree . Thaum qhov yuav tsum tau muaj qhov kub thiab txias tsawg Muaj cov qauv uas tsis muaj qhov kub thiab txias muaj peev xwm siv tau txog li -40 degree, tab sis tus nqi siab dua.
